Eliminate Japanese Beetle Grubs for Ten Years or More!

Provides long term control of Japanese beetles

Safe for people, pets and beneficial soil organisms

Milky Spore is a naturally occurring microscopic bacteria (Bacillus popilliae) that kills Japanese beetle grubs before they can grow into ravenous adults. It's a long-term solution because it survives winter temperatures. The Milky Spore population increases each year, reaching peak effectiveness about three years after application, and lasts ten years or more.

When doing some prep work in my garden, I noticed that I had a large number of grubs. In doing my research, it seems that the best approach would be to do a combination of nematodes and milky spore. The milky spore does not start working until about a year after application and the nematodes will get to work right away. The milky spore is a fine powder and should be applied immediately after or during a rain to help it penetrate into the ground. I found that the best way to accomplish this was to poke a few small holes in one end of a small rectangular disposable aluminum tin. I used an equally sized tin for a lid. I applied during a rain and the powder stayed dry and did not clump. Just tilt the tin and shake. Simple.

I have not applied the Milky Spore yet as the weather has not been appropriate. I am a little concerned that we are at such a high altitude with winter temps that can be well below minus 30, I wonder if grubs can survive at these low temps and if not I wonder if grubs are the problem. I am,however. impressed with the knowledge that your employees have.

Merchant response: The Milky Spore a hard outer shell around each spore that provides natural protection from such temperatures. It is OK to apply if it is not heavily raining and they will survive the winter.

My cousin told me about milky spore and said it has worked for him for many years. I just put this on my lawn a couple of weeks ago. I am very disappointed in how the product is packaged. It is not easy to pour from the plastic bag into the tube applicator. Why is the product not packaged IN the applicator? or at least in packaging that makes it easier to put it into the applicator? After filling the applicator, applying the milky spore is easy; you just walk along and tap it against the ground to apply a small amount to the ground at 4 ft. intervals.

Used this system at my previous yard, after my roses were devoured by Japanese beatles. Once applied, no more trouble, in fact the improvement lasted For many years. Now I am starting at a new garden and saw the J beatles on my roses, so at least this time I know the solution,

Applied this to an old lawn (1950's), which was infested. Horrible. Put it down at a non-optimal time of the Japanese Beetle cycle. Crossed fingers. Next year, saw about a 90% DECREASE in Japanese Beetles! This says it all. Worth every penny, and fun to apply!

I was a bit hesitant to apply Milky Spore for the first time this season because of the product warning labels. However, when I called Gardener's Supply, the help line staff were very understanding and walked me through the process. In the end, the product proved easy to apply.

I did take the extra step of watering this product down after application so our pets wouldn't be exposed. The microbes which go after the grubs aren't harmful to pets, but the white silica dust can be harmful if inhaled (that's why a face mask and gloves are recommended for application). A quick sprinkle with the hose helped the dust to settle into the soil, and I was done!

Judging by the results, this product is apparently safe for our child and pets in addition to the wild bees, birds, and butterflies which frequent our garden. It has also proven extremely effective in eliminating Japanese stinkbugs and beetles in the areas I applied it.

My herb and vegetable gardens were infested last year by both Japanese beetles AND Japanese stinkbugs. In a word, YUK! We have been chasing these bugs out of our home and garden for more than a year. Not only did they eat the buds off of our flowering plants last summer, I found grubs everywhere I dug into the earth to plant my garden this spring.

Thank goodness, combined with good garden care this spring and summer, Milky Spore has vastly reduced our grub and beetle problem. I hope it lives up to its 10-year promise, and I plan to treat a larger area next year. The bugs we did see in our edible garden probably migrated from adjoining flower beds that I did not treat.

In my judgment, this product is well worth the price! Next time, I will be less intimidated by the warning labels.

I've used this every 8 years or so for about 2 decades. It really keeps the beetle population down. I used to pick raspberries and have japanese beetles buzzing me. No longer. And my roses aren't as badly decimated either.
